Definitions

  • This invention relates to valves for controlling the flow of fluids, and particularly to block-and-bleed valves assembled together to form manifolds for controlling the flow of fluids from multiple sources to multiple delivery destinations. Certain concerns unique to the sanitary industry are discussed.
  • Block-and-bleed valves are particularly applicable to the sanitary industry, because they permit control of flow of different types of fluids through the same valve with double protection against intermixing of those fluids. That is, it may be desirable to have chocolate milk flowing through one part of the valve and white milk through another part, or pasteurized milk through one part and raw milk through another part, or clean-in-place solution through one part and milk or another food fluid through another part.
  • chocolate milk flowing through one part of the valve and white milk through another part or pasteurized milk through one part and raw milk through another part, or clean-in-place solution through one part and milk or another food fluid through another part.
  • valves used in the past functioned generally satisfactorily in most instances. Being a single valve, however, it was required to be extremely complex and expensive, including multiple, coaxial, independently operable actuators and valve plugs. Under certain circumstances these valves were subject to substantial leakage and product waste, and when they did fail in this manner, while preventing mix of different fluids, their maintenance was difficult and expensive.
  • This invention relates to improvements to the apparatus described above, and to solutions to some of the problems raised or not solved thereby.
  • the present invention includes a manifold valve assembly, formed of first and second valve bodies, each body having at least one inlet port and a plurality of outlet ports.
  • the two valve bodies are connected together in fluid communication with each other.
  • an actuator assembly which includes a valve actuator and an actuator rod attached to and projecting outward from the actuator, and actuatable by the actuator.
  • a bonnet is affixed to the actuator, insertable into the respective valve body.
  • At least one valve stem is attached to the projecting end of the actuator rod, with plugs on the opposite side of the bonnet from the actuator.
  • the bonnet includes a valve seat for engagement with one of the valve plugs when that valve plug is actuated to a predetermined position by the actuator.
  • the invention replaces a single, expensive, multiple-actuator block-and-bleed valve with several simple, inexpensive single-actuator valves which together are substantially less expensive than the single valve they replace, while still preventing the mixing of different types of fluids, even on failure of one valve seat or valve plug.

  • Fig. 11 is a side elevational view, partially in section, of a manifold valve assembly constructed according to the embodiment shown in Fig. 10.
  • a manifold assembly 10 employing a number of manifold valve assemblies 12 constructed according to one embodiment of the invention.
  • the manifold assembly 10 is connected to and receives supply from a number of sources 14, such as tanks of fluid.
  • the manifold assembly 10 is also connected to and supplies the fluid to a number of destinations 16, such as filler machines for filling containers with one or more of the fluids from the fluid supply tanks.
  • the purpose of the manifold assembly 10 is to control and selectively permit the flow of fluid from one or more predetermined sources 14 to a predetermined destination 16.
  • the manifold assembly includes one supply tube 18 for each fluid supply source 14, and one delivery tube 20 for destination 16. While the manifold assembly 10 shown in Fig. 1 includes only two supplies 14 and two destinations 16, it will be understood that the invention may be equally well applied to any number of supplies and destinations.
  • this manifold assembly results in a crossed pattern of supply tubes 18 and delivery tubes 20.
  • the supply tubes 18 and delivery tubes 20 do not actually intersect, but rather are positioned parallel in sets, in parallel planes, with either one set or the other being in the upper plane, the opposite set being in the lower plane.
  • the delivery tubes 20 are positioned in a plane beneath the plane of the supply tubes 18, but it could just as easily be the other way around.
  • One manifold valve assembly 12 is provided at each crossing point of a supply tube 18 with a delivery tube 20.
  • each manifold valve assembly 12 includes in effect two separate valve bodies, a delivery valve body 22 and a supply valve body 24.
  • Each of these valve bodies 22, 24 is supplied with its own actuator assembly 26, 28 respectively.
  • these valve bodies 22, 24 are connected by a short crossover tube 30.
  • this crossover tube 30 is positioned at the very bottom of each valve body, and oriented substantially horizontally between the two.
  • the supply tubes 18 are positioned in a plane higher than that of the delivery tubes 20, the supply valve body 24 is longer than the delivery valve body 22, by approximately the diameter of the delivery tube and the vertical spacing between the delivery tube and the supply tube.
  • each valve body can been seen by reference to Figs. 4 and 5.
  • Fig. 4 shows the detail of the delivery valve body 22, while
  • Fig. 5 shows the detail of the supply valve body 24. Reference will first be had to the detail of the delivery valve body 22, and this detail will later be related to the detail of the supply valve body 24.
  • delivery valve body 22 includes its own actuator 26, having an actuator rod 32, actuatable between two positions.
  • Valve body 22 has, at its top, a pass-through section including an inlet 36 substantially aligned with an outlet 38. Relating Fig. 4 with Fig. 1, the inlet 36 and outlet 38 of the delivery valve body 22 connect to and in effect form part of one of the delivery tubes 20, permitting free flow of fluid to fluid destinations 16 from upstream destination valves at all times.
  • a valve stem 33 is attached to actuator rod 32 by any suitable, removable means, such as by a threaded attachment.
  • Two valve plugs, an upper plug 40 and a lower plug 42, are attached to or integrally formed with the valve stem 33, both plugs positioned within a valve cavity 44 of the delivery valve body 22 after assembly of the valve stem to the actuator rod 32.
  • Lower plug 42 is positioned on valve stem 33 to be capable of closing a drain port 46 at the bottom of valve cavity 44, while upper plug 40 is positioned thereon to be capable of closing a cavity outlet port 48 at the top of the valve cavity.
  • the actuator 26 basically has two positions, one where drain port 46 is open and cavity outlet port 48 is closed, and the other where drain port 46 is closed and cavity outlet port 48 is open.
  • Valve cavity 44 also has a cavity inlet port 50, which communicates with crossover tube 30, shown in Figs. 1 and 2.
  • supply valve body 24 has its own actuator 28.
  • actuator 28 has an actuator rod 52, actuatable between two positions.
  • Supply valve body 24 has, at its top, a pass-through section including an inlet 54 substantially aligned with an outlet 56. Relating Fig. 5 with Fig. 1, the inlet 54 and outlet 56 of the supply valve body 24 connect to and in effect form part of one off the supply tubes 20, permitting free flow of fluid from fluid sources 14 to downstream supply valves at all times.
  • actuator rod 52 has affixed thereto a valve stem 53, by any suitable removable means, such as by threading.
  • Two valve plugs, an upper plug 58 and a lower plug 60, are affixed to or integrally formed with the valve stem 53.
  • both plugs 58, 60 are positioned within a valve cavity 62 of the supply valve body 24.
  • Lower plug 60 is positioned on valve stem 53 to be capable of closing a drain port 64 at the bottom of valve cavity 62, while upper plug 58 is positioned to be capable of closing a cavity inlet port 66 at the top of the valve cavity.
  • supply actuator 28 has two positions, one where drain port 64 is open and cavity inlet port 66 is closed, and the other where drain port 64 is closed and cavity inlet port 66 is open.
  • Valve cavity 62 also has an cavity outlet port 68, which communicates via crossover tube 30 with cavity inlet port 50 of delivery valve body 22, shown in Figs. 1, 2 and 4.
  • cavity inlet port 66 When cavity inlet port 66 is closed, the fluid in inlet 54 is not permitted to enter cavity 62, and continues out outlet 56, possibly to the next manifold valve assembly 12.
  • actuator 28 moves actuator rod 52 to its other position, taking valve stem 53 and valve plugs 58, 60 with it, cavity inlet port 66 is opened and drain port 64 is closed, permitting flow of fluid into the cavity 62 via the cavity inlet port 66 and permitting flow of the fluid out of the cavity via cavity outlet port 68.
  • Control of the two actuators 26 and 28 is coordinated so that when cavity outlet port 48 of delivery valve body 22 is open, cavity inlet port 66 of supply valve body 24 is also open. Fluid then flows from supply tube 18 into supply valve cavity 62, through crossover tube 30, into delivery valve cavity 44, and finally into delivery tube 20.
  • the length of the delivery valve stem 33 must differ from the length of the supply valve stem 53 by the same amount. That is, because the supply valve body 24 is longer than the delivery valve body 22, the delivery valve stem 53 will also be longer than the supply valve stem 33 by about the same amount. As can be seem by comparing Fig. 4 to Fig. 5, that difference is applied to the distance between respective pairs of valve plugs, so that the distance between delivery valve plugs 40 and 42 is smaller than the distance between supply valve plugs 58 and 60 by substantially the same amount.
  • the actuators 26, 28 are coordinated to normally work together. Otherwise the supply valve cavity inlet port 66 could be open while delivery valve cavity outlet port 48 is closed, causing supply fluid to drain continuously out delivery valve drain port 64. Accordingly, any malfunction of any part of the manifold valve assembly 12 must be quickly restored to proper function to minimize waste. However, once the number of manifold valve assemblies 12 is assembled into the manifold assembly 10, usually by welding, there would be no practical means to easily remove and/or replace a single valve body.
  • the invention calls for structure permitting easy removal of the actuator and valve stem from any one of the valves at any time.
  • This feature of the invention can best be set forth by reference to Fig. 6, using a delivery valve body 22 as an example, although it clearly applies equally to the supply valve body 24 in this embodiment.
  • the body 22 is formed by the assembly of a valve bonnet 70 into a valve body proper 72, the latter having substantially all the ports 36, 38, 46, 50 referred to above.
  • the only port formed specifically by the bonnet 70 is the cavity outlet port 48, in the following manner.
  • valve stem 33 is inserted upward through an opening 78 in the bonnet 70 and attached to actuator rod 32.
  • the actuator 26, with the valve stem 33 attached to its actuator rod 32, is then affixed to a flat top surface 74 of the bonnet by any suitable removable means, such as threaded fasteners 76.
  • the bonnet 70 has a flange 80 which flares outward from the central opening, to fit onto a mating flange surface 82 of the body proper 72. Upon assembly the two flanges are clamped together by a suitable clamp 84 (Fig. 4).
  • annular ridge 83 is provided in the facing surface of the bonnet flange 80, which engages a matching annular channel 85 formed in the facing surface of the mating flange surface 82, to aid in alignment and assembly.
  • the bonnet 70 includes a shoulder 86 which, together with a facing shoulder structure 88 in the body proper 72, permits spacing for sealing means, such as an O-ring 90 (Fig. 4).
  • the bonnet 70 has a cage portion 92, with large openings or gaps alternating with separated bars 93.
  • the cage portion 92 is about the same in length as the inlet port 36 and outlet port 38 are in width.
  • sealing means 98 can best be described as either a gasket having enlarged side edges or a pair of O-rings integrally connected by a web.
  • the ring portion 94 has an inner beveled area 100 at its distal end which constitutes a valve seat into which plug 40 is sized to tightly fit.
  • valve stem 33 is inserted through opening 78 in bonnet 70 and attached to actuator rod 32, the entire assemblage is then inserted into the body proper 72 and clamped therein.
  • the clamp 84 is opened and the actuator and bonnet 70 removed.
  • the structure of the present invention replaces a single, expensive, multiple-actuator valve with a pair of simple, inexpensive single-actuator valves which together are less expensive than the single valve they replace, while still preventing the mixing of different types of fluids, even on failure of one valve seat or valve plug. It is not uncommon for the single valve of the prior art to be three times as expensive as one of the simple valves provided by the present invention. Accordingly, even though the present invention requires in effect two valves where the prior art used one, the cost of the structure of the present invention is still less than the prior art by a third or more.
  • the delivery tubes 16 are smaller in size than the supply tubes 14, such as 2 inch delivery tubes being used with 3 inch supply tubes.
  • the total drain opening area of the manifold valve assembly 12 is at least as large as the smaller of the supply tubes 14 or the delivery tubes 16. In most prior art valves, this requirement adds to the expense of the valve, requiring a large single opening.
  • two drain ports are provided, one drain port 46 in the delivery valve body 22 and one drain port 64 in the supply valve body 24. It is the sum of the areas of these two drain ports that must at least equal the area of the smaller of the supply tube 14 or delivery tube 16.
  • Each separate drain port 46, 64 can, then, be substantially smaller than either the supply tube 14 or the delivery tube 16. This has the further advantage of permitting the relative reduction of the size of the valve cavities 44, 62, reducing waste of product. Waste is reduced because each time the valve actuators 26, 28 switch from open to closed, the entire volume of fluid in both valve cavities 44, 62 is drained out the respective drain port. If the volume of these cavities is reduced, the volume of fluid wasted in switching is also reduced. Even further, as shown in Fig. 7, a bonnet 70a may be provided with a smaller seat 100a, the diameter of the seat being reduced to substantially the size of the delivery tube 20. This bonnet 70a permits reduction of the size of the plug 40a, further reducing waste.
  • Figs. 8 through 11 show manifold valve structure to accomplish the same objects, but from a slightly different approach. In the embodiments shown in those figures, only one specialized valve body is used, with the remaining control provided by simple shut-off valves.
  • a manifold valve assembly 112 having a supply valve body 24 exactly as described above with reference to Figs. 1 through 3 and particularly Fig. 5.
  • supply valve cavity outlet port 68 is connected to a short length of tubing 114 and an elbow 116, in turn connected to the inlet 118 of a conventional shut-off valve 120.
  • the type of shut-off valve 120 selected is the type with a T-body, as the shut-off valve still needs to be connected into the delivery tube 20 and permit pass-through of the fluid in the delivery tube.
  • the flow within manifold valve assembly 112 begins when actuator 28 opens cavity inlet port 66 and closes drain port 64.
  • shut-off valve actuator 126 withdraws plug 142 from shut-off valve outlet port 148.
  • the fluid flowing into cavity 62 then continues and flows through tubing 114 and elbow 116, and thereby through shut-off valve 120 and into delivery tube 20.
  • Manifold valve assembly 212 includes a supply valve body 222 substantially identical to delivery valve body 22 (Figs. 1 through 4 and 6), including the fact that the valve cavity 244 is shorter than the valve cavity 62 of supply valve 24 (Fig. 8). The only difference is the way the valve body 222 is connected into the manifold 10, that is, in such a way that the flow within the valve body is reversed from that described in reference to delivery valve body 22.
  • shut-off valve actuator 126 simultaneously withdraws plug 142 from shut-off valve outlet port 148.
  • the fluid flowing into cavity 244 then continues and flows through tubing 114 and elbow 116, and also through an extension 117 which must be provided because shut-off valve 120 is higher in assembly 212 than in assembly 112 to align with the relatively higher delivery tube 20. The fluid is thereby passed through shut-off valve 120 and into delivery tube 20.
  • the manifold valve assembly 312 there shown includes three valves, two conventional shut-off valves 120 with T-bodies, with their inlets both connected, via respective extensions 117, elbows 116 and tubes 114, to separate outlets of specialized valve body 322.
  • Valve body 322 is substantially the same as valve body 222, with the exception of the second outlet, for connection to the second shut-off valve.
  • This arrangement permits, with the use of only one specialized valve body 322, the control of flow from a source 14 to two destinations 16, further reducing the total cost of the manifold without any loss of control and with reduced waste.
  • Manifold valve assembly 312 replaces two of the previous, expensive valves, with a cost factor still less than one of those prior valves, while still preventing the mixing of different types of fluids running through the same valve assembly, even on failure of one valve seat or valve plug.
